【摘要】 介绍了已有的农田蛾类昆虫检测装置和相关研究技术。在已有技术的基础上,介绍了图像的预处理和杂质点的消除方法。在对提取的图像进行分割时,首先介绍使用Otsu方法来对图像进行分割,接着采用sobel算子提取蛾类对象的边缘,以边缘像素为种子点,使用区域生长来对蛾类图像进行分割。通过比较这两种分割方法可知,使用区域生长方法对蛾类图像分割的效果较好。更多还原

【Abstract】 This paper first to introduce the technology of the detection equipment about moths in agricultural field.base on these technology,it introduces the previous processing of image and the filtering of impurity points.when segmenting the moths digital image,.This paper first to introduce the method of Otus for segmentation about digital image,after to introduce another method that to use sobel algorithm to get the boundary pixels of moths in digital image and to use these boundary pixels as seed points,to use the region growing to segment the digital image of moths,comparing these two methods,the region growing method is better in image segmentation about moths digital image.更多还原
